Final answer:
Homeostasis is related to physiological processes that maintain stable conditions in a biological system in response to environmental changes. The correct answer to the student's question is 'B. Physiological'.
Step-by-step explanation:
Homeostasis is fundamentally about the physiological processes responding to stimulus. It is the ability of a biological system to maintain stable internal conditions despite changes in external environment. In a biological context, the processes that make up homeostasis are all physiological, as they pertain to how an organism's body functions internally to maintain a stable and constant condition. Growth and dynamic homeostasis of a biological system, which includes cells, organisms, populations, and ecosystems, are continuously responding to external environmental changes. The proper response to the student's question would be 'B. Physiological.'
